Specification of Letters Patent. Mopllcstion filed May 13, will). EerieNo. 562,033.

To all whom it may concern:

Be it known that 1, JOHN P. BADEN- Iii ween, a citizen of the UnitedStates, residing at Seattle, in the county of King and State ofvV'ashingtonJuwe invented new and useful Improvements in Steamenerators,

' of which the following is a specification.

My present invention has to do with steam generators, end is designedmore perticu larlyas on improvement upon the generator constituting thesubject. mutter of my Letilegrs-l utent No. 862,872, granted August 13,:L' 07. l

The object of the present invention is lac-provide a simple generatorcomprising o steam drum, a Water drum and s mud drum, connected togetherand communicating with cools other through interposed tubes, and

constructed and arranged in such-manner.

that all strains incidental to contraction and expansion are taken. careof and prevented from deteriorating the generator.

The invention will be best understood by reference to the followingdescription when taken in connection with the accompanying illustration.of one specific embodiment thereof, while its scope will be moreperticulurly pointed out in the claim appended,

in the drawings which are hereby mode it port hereof Figure 1 is s.View, partly in longitudinal vertical section and partly 1n elevation,of my improved wsitentubc steam generator. Fig. 2 is u :i'ront eietstiouof the generator with a. portion of the front wall of tile casingremoved, Fi 3 is s deteii View showing by full lines be arrangement ofone longitudinal beam in the channeled seat utthe upper end of oneupright, and.

the interposition of the said beam between the said upright undone ofthe saddles.

Similar letters designate corresponding ports in both views of thedrawings, referring-to which:

A is the casing of the-generator; This casing may be, of theconstrtictiouillustrsted or of any other construction consonant to thepurpose of my invention, and is provided at a with an outlet forproducts of combustion.

B is a furnace located in the lower front portion of the casingondha'vlng tlie'ususl, grate D and bridge wall a.

G and ID are lower and uuper, suitably supportcd bullies, and E is utrue-averse eruns, wnemuo'ron. H

l ll are horizontal and parallel l-beams superposed on uprights G anddisposed in channeled seats a at the upper ends of said uprights.

ll is the steam drum; 1, the water drum, sud J, the mud drum, all threeof which-ore wronged transversely of the casing, essliown. The steamdrum H is supportcd'b 7o saddles K, preferably of cost-iron, Wliic reston the iii-booms F, while the Water drum is hung from the said beams Fthrough the medium of bolts L, suitably connected with the beams anddrum.

interposed between end connecting us weil as reflecting communicationbetween the steam drum H and the Water drum 1 is u, group of Water-tubesM, and connected with the mud drum J are twogroups ll sud, lif w ofWater tubes, which serve to suspend the mud drum from the stem: driunend the Water drum, respectively, us well us to comb? lislicommunication between the some; the group F, by preference, corn risinge. greater number of tubes than cit lei group M or'll in about theproportion illustrated.

R is :1 water column, and S and T are lower and upper pipes which effectconimuniczition between said column and the inso terior of the steamdrum H in the manner shown in Fig. 1 or in any other approved manner. lThe three drums H, l and J supported and connected together in themanner de- 95 scribed constitute u simple sud l'iighly eili: cientgenerator; the l'utterbelng largely due to the foot that'the circulationof steam and, Water through the Water and steomjeontsm:

iug elements is continuous end wilih o miui itiu mum of breaks andinterruptions." It will also be noted here that by reason oii'tlie'drums bcin connected through nterposed tubes and tie steam drum andwater drum being supported, by e metal framework- While the, mud drum ishung through the tribe's from' tlie steam drum and Water drum end solelysupported by sold tubes, ell

rom shortening the v the generator.

I to the fact that gitndinal beams standing strains due to contractionand expansion are "rovided for and are effectually prevented period ofusefulness of This is duein large measure the arrangement of the lon- Fin the channeled seats d atthe upper ends of the. uprights Ur,v enablesthe said beams F to work or move end"- wise between the uprights and thesaddles, and hence permits of expansion and contraction of the tubes Mand P, notwiththe connection of the drum I to the beams F through themedium of the hangers L.

While I have shown and described one form of my invention, it is to beunderstood that I am not limited to the details or the form'or relativearrangement of parts disclosed, but that modifications may be madetherein without departing from the spirit thereof.

Having described my invention, What I claim and desire to secure ent,1s:

A steam generator comprising uprights L saddles resting on the saidlongitudinal,

beams, hangers connected with the beams, and spaced drums connectedtogether and communicating with "each other; one of the said drumsresting in the said saddles, and

another drum being connected to the said hangers.

Intestimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
